NS_species_params: Example species parameter set based on the North Sea

In mizer: Dynamic Multi-Species Size Spectrum Modelling

Example species parameter set based on the North Sea

Description

This data set is based on species in the North Sea (Blanchard et al.). It is a data.frame that contains all the necessary information to be used by the MizerParams() constructor. As there is no gear column, each species is assumed to be fished by a separate gear.

Usage

NS_species_params

Format

A data frame with 12 rows and 7 columns. Each row is a species.

species

Name of the species

w_max

Computational upper size boundary, defaulting to 1.5 * w_inf.

w_mat

Size at maturity

beta

Size preference ratio

sigma

Width of the size-preference

R_max

Maximum reproduction rate

k_vb

The von Bertalanffy k parameter

w_inf

The von Bertalanffy asymptotic size. This is the required maximum-size parameter.

Source

Blanchard et al.

Examples

params <- newMultispeciesParams(NS_species_params)
